摘要
由于气体的高速流动 ,产生了湍流效应 ,而湍流效应的存在 ,又影响了储层的渗流特性。为了正确评价储层特性和对产能作出正确的预测 ,给出了湍流系数D的三种计算公式 ,并进行了对比选择 ,确定了适合大庆油田地质特点的一种计算方法 ,同时 ,对湍流影响进行了修正 ,并将之应用到气井评价中。
High velocity gas flow causes turbulence coefficient, while the existence of turbulence effect affects percolation flow characteristics of a reservoir.To properly evaluale reservoir characteristics and correctly predict the productivity, this paper gives out three calculation formulas of turbulence coefficient D, and makes comparison and selection of the three, and fixes a calculation method suitable for geologic characteristics of Daqing oilfield, at hte same time, turbulence effect is corrected and is applied to gas well evaluation.
